data and not sample data using sample data for this is like putting bricks in

00:32

your backpack they'll fit in there but it makes no plan so statement 3 is [boy walking with bricks in his backpack and falls over]

00:37

inaccurate making answer C and D wrong so just cross them out reviewing

00:42

00:46

tendency it is a measure of variability and that means statement 2 is false and

00:52

answers B and E are off our list cross em off, there we go. So it looks like

01:01

population is a measure of central tendency central tendency refers to the [Option A circled yellow]

01:06

middle value of data and is measured using the mean median or mode well the
